What is CVE-2026-3774?
CVE-2026-3774 is a medium-severity vulnerability in Foxit Pdf Editor, published on 1 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
The application allows PDF JavaScript and document/print actions (such as WillPrint/DidPrint) to update form fields, annotations, or optional content groups (OCGs) immediately before or after redaction, encryption, or printing. These script‑driven updates are not fully covered by the existing redaction, encryption, and printing logic, which, under specific document structures and user workflows, may cause a small amount of sensitive content to remain unremoved or unencrypted as expected, or result in printed output that slightly differs from what was reviewed on screen.
